Now i finally solved it on my own.
The problem was , as mentioned above, that the libdb-4.5 version of
kolab doesn't work without threads on apache2 threaded.
This is the same problem as mentioned in my fist post 2006 !
So, i build a statically linked debian version of db-4.5 and changed
the --with-db4=/kolab to the statically linked target.
Now ot works but how to migrate old (incompatible) syncKolab adresses ?!?
Perhaps anyone can give a hint on it.
kind regards
Franz
